  • the invention relates to a method for routing a connection from a first mobile station to a second mobile station by way of at least one further mobile station in a wireless communication system, and also a corresponding wireless communication system and a central routing device, and also a mobile station for a wireless communication system.
  • cellular mobile wireless networks are known in which the individual wireless cells are supplied by a base station in each case.
  • Known standards for cellular mobile wireless networks are for example GSM (Global System of Mobile Communication) and UMTS (Universal Mobile Telecommunications Standard).

  • the data for the connection is then either transmitted directly to the destination mobile station (insofar as the latter is likewise located in the same wireless cell) or it is transmitted to a second base station in whose wireless cell the destination mobile station is located and which then transmits the data for the connection to the destination mobile station.
  • ad-hoc networks which are formed simply by mobile stations without any use being made of base stations with their wireless cells.
  • the mobile stations assume a relay function with the result that data for a connection is forwarded from a start mobile station to a destination mobile station directly by way of one or more other mobile stations.
  • the routing in an ad-hoc network is carried out according to certain algorithms by the participating mobile stations themselves.
  • the start mobile station for example sends an address of the destination mobile station to all the mobile stations surrounding it in order to signal its connection request. This signaling information is passed on by the surrounding mobile stations until it reaches the destination station.
  • the addresses of the neighboring mobile stations on the determined route are stored in the participating mobile stations in each case for the route which is ultimately successfully established.
  • mobile wireless systems are known in which in the case of a cellular network structure mobile stations are used which are also capable of communicating directly with one another in the manner of an ad-hoc network. In this manner, for example, gaps can be closed between the individual wireless cells of the cellular network across a plurality of mobile stations as relay stations.
  • Such types of cellular mobile wireless networks with an ad-hoc component are described for example in Y.-D. Lin et. al. “Multihop Cellular: A new architecture for wireless communications”, IEEE INFOCOM 2000, pp. 1273 to 1282, H.WU et. al. “Integrated cellular and ad-hoc relaying systems: iCAR”, IEEE Journal on selected areas in communications, Vol. 19, No. 10, October 2001, pp.
  • the routing from mobile station to mobile station takes place in the normal manner described above of an ad-hoc network. That part of a connection which is conducted by way of the base stations in the network is however routed as in the case of a known cellular mobile wireless network, in other words through a generally central routing device in the network.
  • One possible object of the invention is to implement the routing of a connection from a first mobile station to a second mobile station by way of at least one further mobile station, such as is necessary for example in an ad-hoc network, in an advantageous manner.
  • positional information is initially acquired by way of the mobile stations.
  • a central routing device determines a route for the connection based on the acquired positional information and generates corresponding routing information which is afterwards transmitted to the mobile stations participating in the connection.
  • the mobile stations communicate directly with one another.
  • the further mobile stations therefore have a relay function for the data of the connection to be transmitted from the first mobile station to the second mobile station.
  • Positional information comprises information about the geographical position of the mobile stations which is suitable for defining the mutual arrangement of the mobile stations in the wireless communication system such that the routing can be performed on the basis of this positional information.
  • this can for example be position coordinates determined by a position determination system such as GPS for example.
  • the method and devices described herein may provide a special routing device for this purpose.
  • the central routing device can take into consideration the positional information acquired from a large number of mobile stations during routing. In an extreme case this can affect all available mobile stations. In this manner, an optimum route can be determined in a simple manner.
  • the execution of routing by the central routing device enables a reduction in power consumption for mobile stations and a reduction in the signals exchanged between the mobile stations when compared with the execution of routing by the mobile stations themselves, as is the case with the related art.
  • Mobile station here is understood to be any mobile wireless station which is provided for use in a wireless communication system and which is capable of maintaining direct communication with another mobile station.
  • the mobile stations are located in wireless range of at least one base station of a cellular mobile wireless network.
  • the routing device then transmits the routing information to the base stations which perform onward transmission of the routing information to the mobile stations.
  • This means that the mobile stations are operated with a relay function in the coverage area of the cellular mobile wireless network.
  • the routing for the direct relay connections between the mobile stations is also not performed by the mobile stations themselves but by the central routing device connected to the base stations of the cellular mobile wireless network.
  • the method and devices described herein may make it possible for the connection between the first mobile station and the second mobile station to be simply a section of a longer connection between further mobile stations.
  • a partial connection can initially be established for example by way of one or more base stations in the cellular network to the first mobile station and/or from the second mobile station by way of one or more base stations a further partial connection to the destination station of the overall connection.
  • the connection between the first and the second mobile station is then simply a partial connection of the overall connection between start station and destination station.
  • the mobile stations determine their positional information themselves and transmit it for acquisition purposes to the base stations.
  • the base stations can then advantageously transmit the positional information to a central storage device which the routing device can access in order to determine the route.
  • the mobile stations have a first operating mode in which they are operated in the cellular mobile wireless network in accordance with a first wireless standard.
  • This first wireless standard can be any desired standard for a cellular mobile wireless network such as GSM or UMTS for example.
  • the mobile stations have a second operating mode in which they form an ad-hoc network with one another in accordance with a second wireless standard. These are therefore referred to as so-called dual-mode mobile stations.
  • dual-mode mobile stations During the connection for which the routing device determines the routing information the mobile stations are operated in the second operating mode.
  • an ad-hoc network is understood to be a mobile wireless network in which the individual mobile stations exercise relay functions for the transmission of data for a connection.
  • the wireless communication system then relates to two superimposed networks, namely the cellular network and the ad-hoc network.
  • the mobile stations are only placed in the second operating mode when the cellular mobile wireless network reaches a limit value for its capacity loading.
  • the use of the relay function of the mobile stations serves simply to increase the overall capacity of the wireless communication system, insofar as this is necessary. If this is not required, it is possible to dispense with the determination of the routes by the central routing device on the basis of the acquired positional information and with the transmission of the corresponding routing information to the mobile stations, and instead the routing can take place as normally occurs in known cellular mobile wireless systems.
  • the resource requirement for determining the route is kept small while the limit value for the capacity loading remains unexceeded. It is however also advantageous if the routing device handles the routing both for the ad-hoc network and also for the cellular network.
  • the second mobile station makes available a particular service.
  • Service information concerning the service made available by the second mobile station is stored in a storage device, which information is communicated to the first mobile station.
  • the first mobile station On the basis of the service information notified to it, the first mobile station then signals to the routing device that it should access the service.
  • the routing device then establishes the connection from the first mobile station to the second mobile station by generating the corresponding routing information.
  • Service here is understood to comprise any desired service within a mobile wireless network to which a mobile station is able to offer access. With regard to such a service, it can for example be a case of a location dependent service which makes available for example information about restaurants or cinemas situated in the vicinity depending on the position of a mobile station.
  • a further service is for example the provision of access to the internet or to other networks.
  • the base stations broadcast the service information stored in the storage device (broadcasting).
  • Service information concerning services made available by a large number of mobile stations can be stored in the storage device and be notified to the other mobile stations by broadcasting from the base stations. Any mobile station is then able to request a connection to the desired service from the central routing device. Since the position of any mobile station situated in the mobile wireless system can be acquired, the routing device also has a knowledge of the position of the mobile station offering the service in question. On receiving a request for the corresponding service, it can therefore establish a connection to the mobile station offering this service.
  • the routing information contains details concerning the transmit power level with which the mobile stations participating in the connection are to operate the connection. Since the routing device has a knowledge of the position of the participating mobile stations, it also knows the distances between the mobile stations and can therefore calculate the transmit power required for the transmission to the next mobile station within the route. In this manner, it is possible to minimize the transmit power required overall in the system and interference effects are reduced to a minimum.
  • the routing information contains details concerning which transmission resources the mobile stations participating in the connection are to reserve for the connection.
  • “Transmission resources” here is understood to include all the wireless resources required for the transmission, for example frequency ranges in the case of an FDMA system, spread codes in the case of a CDMA system and time slots in the case of a TDMA system.
  • the routing device instructs the mobile stations participating in the connection to terminate the reservation of the transmission resources for this connection. In this manner, the previously reserved transmission resources are available once again for the establishment of new connections.
  • the wireless communication system and also the central routing device and the mobile station for a wireless communication system comprise the components needed to implement the method and are designed in a corresponding manner.

  • FIG. 2 shows an embodiment of a mobile station for the wireless communication system shown in FIG. 1 .

  • the second mobile wireless station MS 2 communicates service information SI to the base station BS, which describes the service made available and is stored by the base station BS in a central storage device M in the mobile wireless system in relation to an identifier of the second mobile station MS 2 .
  • All mobile stations MS 1 to MS 5 currently operating in the mobile wireless system periodically send positional information PI 1 to PI 5 to the base station BS which stores this information similarly in relation to the respective mobile station in the central storage device M.
  • the positional information PI 1 to PI 5 describes the geographical position of the respective mobile station MS 1 to MS 5 in the relevant wireless cell of the mobile wireless system.
  • the positional information PI 1 to PI 5 is determined by the mobile stations MS 1 to MS 5 by GPS receivers. With regard to other embodiments, the positional information PI 1 to PI 5 can also be determined by the base stations BS in the mobile wireless system instead of by the mobile stations MS 1 to MS 5 . Methods for determining the position of a mobile station in a cellular mobile wireless system are adequately known to the person skilled in the art and will not be described further here.

  • the routing device R ascertains that the second mobile station MS 2 is offering the service required by the first mobile station MS 1 .
  • the routing device R then calculates a route, optimized to the greatest possible extent, for a connection V between the first mobile station MS 1 and the second mobile station MS 2 .
  • this connection V passes from the first mobile station MS 1 by way of the third mobile station MS 3 to the second mobile station MS 2 .
  • more than one mobile station MS 3 is defined as a relay station for establishing the connection V.
  • the routing device R considers the geographical position of the mobile stations and attempts to implement a path which is as short as possible in order to minimize the transmit power needed for the connection V.
  • the routing device R considers to what extent resources of the mobile stations MS 1 -MS 5 in the form of frequency ranges, spread codes or time slots have already been reserved by other connections.
  • the routing device R in FIG. 1 generates routing information RI, corresponding to the route it has determined, which it transmits to the base station BS for those wireless cells in which the mobile stations MS 1 , MS 2 , MS 3 participating in the connection V are situated.
  • the base station BS broadcasts this routing information RI such that it can be received by the mobile stations MS 1 to MS 3 concerned.
  • the routing information RI notifies the mobile stations MS 1 to MS 3 about the mobile station MSi from which they are to receive data relating to the connection V for onward transmission as a relay station and to which mobile station MSi they are to forward this data. For the first mobile station MS 1 there is no preceding station in the route for the connection V because it is the start station.
  • the routing information RI for the third mobile station MS 3 tells the latter that it is to receive data from the first mobile station MS 1 and forward it to the second mobile station MS 2 .
  • the second mobile station MS 2 learns by way of the routing information RI that it is to receive transmissions from the third mobile station MS 3 for the connection V.
